Dear Mr. Bliss:
SUBJECT:
REVISED SAFETY EVALUATION FOR EXEMPTIONS FROM 10 CFR 50 APPENDIX R, SECTION III.G (TAC N0s, 57282, 57283, 61291, 61292, 62024, 62025, 63556, AND 63557)
By letter dated December 11, 1987, the NRC staff issued a Safety Evaluation Report (SER) to address exemption requests from the regulatory requirements of 10 CFR 50, Appendix R, Section III.G submitted by Comonwealth Edison Company (CECO, the licensee) for the Quad Cities Nuclear Power Station (QCNPS).
Subsequently, CECO reviewed our SER for consistency with the as-built configu-ration of QCNPS and provided us with their documented coments, as well as applicable justifications, on February 19, 1988. The NRC staff evaluated these corments and incorporated those that were germane. Consequently, in response to CECO coments offered on February 19, 1988, we revised our previous SER on Appendix R.Section III.G. The revised SER is enclosed herein, and shall re-place the previous SER of December 11, 1987 in its entirety. However, the cover letter for this previous SER is still appropriate. Although, CECO should be made aware that the date identified as September 9,1987 in the cover letter (for an NRC site visit) is erroneous. The site visit was actually conducted on that day in 1986.
Sincerely,
/5 Thierry Ross, Project Manager Project Directorate III-2 Division of Reactor Projects - III, IV, V and Special Projects

Mr. L. D. Butterfield, Jr.
2 which detailed the chronology of their submittals requesting schedular exemptions for QCNPS from 10 CFR 50.48, including related status updates on completion of Appendix R modifications.
To date, all plant modifications required to comply witn Appendix R (except for exemptions that were granted or are pending) have been completed, with only two exceptions. As such t excluding emergency lighting and RCIC valve related modifications, schedular exemptions from 10 CFR 50.48 are no longer necessary. Consequently, the staff considers the status of these schedular exemption requests to be moot, and does not plan any further review effort.
The two outstanding modifications will be addressed at some later date.
With regard to a letter dated April 9,1987, CECO requested NRC staff approval to replace the foam water spray system, used to protect recirculation pump motor generator (MG) sets, with a standard water spray system. Additionally, this letter highlighted a previous modification in the associated fire detection system which resulted in installation of compensation type thennostats vice flame or infrared detector. The staff recognizes this plant alteration of fire protection features for the recirculation pump MG sets and finds them acceptable.
Based upon CECO coments provided by their letter dated February 19, 1988, NRC staff revised the Safety Evaluation enclosed in our letter dated December 11, 1987. The SE enclosed in this letter shall be considered to supersede the December 11, 1987 SE in its entirety.
Sincerely, l
Thierry M. Ross, Project Manager Project Directorate III-2 Division of Reactor Projects - III, IV, Y and Special Projects
